Marlowe: Test 2

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, which can occur in a vacuum.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is an example of conduction in everyday life?

Back

Ironing a shirt is an example of conduction, where heat from the iron is transferred to the fabric.

Front

What is an example of convection in everyday life?

Back

Boiling water is an example of convection, where hot water rises and cooler water sinks, creating a circular motion.

Front

What is an example of radiation in everyday life?

Back

Feeling warmth from the sun is an example of radiation, where heat travels through space to reach us.

Front

What is the role of control variables in an experiment?

Back

Control variables are the factors that are kept constant to ensure that the results of the experiment are due to the independent variable.
